9 Claims.

This invention relates to pile floor coverings. of which a carpet istypical, land to a broad width carpet composed of carpet strips seamedtogether at their uncut selvage vedges and to the method of weaving suchcarpet strips.

In order to make a. carpet of more than a single strip in width it isnecessary to seam together, either by sewing or by adhesive tapes on thebacks, strips of carpet at their selvage edges as, for example, to makea broad width carpet, re-

composed of 'narrow strips of carpeting. It has long been a diiliculty,however, that if the selvage edges of a pair of carpet strips are unitedin a seam an objectionably bulky ridge along the seam results and toobviate this it has been common to cut oi! the selvages and even aportion of the adjacent pile rows before seaming. But this in turn hasnecessitated some provision, such as adhesive applied to the back of thecarpet, to permit the carpet to be handled without fraying after it hasbeen cut.

An object of the present invention is to provide a carpet which obviatesthese difficulties and to that end I have devised a novel selvageconstruction in which the pile is woven closely adjacent to the edgesand the carpet is therefor adapted for seaming without forming a ridgeand therefor without the need for cutting near the selvage. There isconsequently no need for frayproofing the carpet with an adhesive.

It is a further object of my invention to provide a novel carpet stripwhich can be used either for joining with another strip or alone where asingle strip of carpet is desired.

In the drawing:

Fig. 1 is Ia plan view of 'a carpet formed by seaming together twocarpet strips;

Fig. 2 is an enlarged weftwise section taken on the line 2--2 of Fig. 1,showing the pile tufts in elevation.

Fig. 3 is a perspective view of a piece of my novel carpet showing theselvage; and

Fig. 4 is a modification.

The carpet 2, Figs. 1 and 2, is made of two strips A and B securedtogether at their abutting selvage edges by a tape 4 adhesively securedacross the seam. Each of the strips A and B is made of a backing fabrichaving in the body of the fabric wefts 6, 1, binder warps 8a and 8b andstuffer warps I0, and having at the selvage edge a selvage cord I4. Theupper wefts 6 are the holding weft shots around which the pile warps arewoven to form the pile elements, i. e., loops or tufts, such as the piletufts which are formed by the usual pile warps which are not shown inthe drawings, for the purpose of clarity. The tufts are shown in Figs.2, 3 and 4 in full side view for the same purpose. The carpetillustrated is of the tapestry type in which theV pile weft formed at I2draw in `the selvage cord I4 close to the bases or roots of the tufts ofthe selvage pile row 20a and draw in also the lower loops of the binderwarps to a position under the roots of the pile tufts in the selvagepile row, thereby the pile tufts are woven close to the edge of thecarpet, there is no protruding margin of the backing fabric at theselvage and the are oi' the pile tufts extends laterally over theselvage cord I4, Fig. 2.

Thus, when the edges of two strips of such carpet are abutted, as shownin Fig. 2, the omission of the stuffer warps at the selvages eliminatesthe ridge and the space 25a between the tufts at the seam, correspondingto the space 25 between adjacent tufts is so narrow that the outwardflare of the upper portions of the tufts conceals the seam formed'at theabutting selvage edges.

Fig. 4 shows a modification of my invention in which the stuffer warpsIll and selvage cord I4 are retained and the binder warp 8c at theselvage, shownin Fig. 2, is omitted so that the bights I2 of the weftsdraw in the selvage cord I4 close to the roots of the pile tufts and tothe stuffer warps.

Thus, with the normal pile flare adjacent the selvage, I conceal theseam and avoid a ridge at the seam by reducing the bulk of the backingfabric at the selvage by the omission of certain warps adjacent the edgeof the carpet strip which are woven in the body of the fabric.

Two pieces of carpet A and B, constructed as above described. may bejoined at their abutting selvage edges with an adhesive tape 4, Fig, 1,so that the pile is continuous across the seam with no interruption ofthe pattern and with no appreciable ridge over the seam.

An advantageous feature of my invention is that the carpet strips thusconstructed are not only adapted for seaming together in the mannerdescribed without the necessity of cutting the selvage before seaming orof frayproofing the carpet, butv they are also provided with a rmasians3 ,ly bound selvage edge so that the carpet strip can also be used alonein situations where a single carpet is desired.

I have illustrated a tapestry carpet, but my invention can likewise beembodied in other types of pile floor coverings such as jacquard wovencarpets.

I claim:

l. A broad width pile carpet composed of narrow strips of carpet, eachstrip having a selvage edge seamed by a tape to the abutting selvageedge of an adjacent strip, each oi.' the strips having in the bodyportion thereof wefts, binder warps, stutter warps and pile elements,and having a selvage portion comprising a selvage cord and a row ofselvage pile elements, in which selvage portion certain of the type ofwarp present in the body of the carpet are omitted, the selvage cord.being snugly adjacent the roots of the selvage pile elements, wherebythe outward flare of the pile adjacent the selvages oi the abutted edgesof the carpet strips conceals the seam between said strips.

A broad width pile carpet composed or" narrow strips of carpet, eachstrip having a selvage edge seamed by a tape to the abutting yselvageedge of an adjacent strip, each of the strips having in the body portionthereof wefts, binder warps, Studer warps and pile elements, and havinga selvage portion comprising a selvage cord, binder warps and a row ofselvage pile elements and without stufer warps, the selvage cord beingsnugly adjacent the roots oi' the selvage pile elements, whereby theoutward flare of the pile adjacent the selvages of the abutted edges ofthe carpet strips conceals the seam between said strips,

3. A broad width pile carpet composed of narrow strips of carpet, eachstrip having a selvage edge seamed by a tape to the abutting selvageedge of an adjacent strip, each oi the strips having in the body portionthereof wefts, binder warps, stuier warps and pile elements, and havinga selvage portion comprising a selvage cord, stuffer warps and a row ofselvage pile elements and without binder warps, the selvage cord beingsnugly adjacent the roots of the selvage pile elements, whereby theoutward are of the pile adjacent the selvages of the abutted edges ofthe carpet strips conceals the seam between said strips.

4. A carpet strip having in the body portion thereof wefts, binderwarps, stuer warps and pile elements, and having a selvage portioncomprising a selvage cord and a row of selvage pile elements, in whichselvage pcrtion'certain of the type of warp present in the body of thecarpet are omitted, the selvage cord being snugly adjacent the roots ofthe selvage pile elements and the outward nare of the pile adjacent theselvage extending laterally over the selvage cord.

5. A carpet strip having in the body portion thereof wefts, binderwarps, stuer warps and pile elements, and having a selvage portioncomprising a selvage cord, binder warps and a row of selvage pileelements and without stutter warps, the selvage cord being snuglyadjacent the roots of the selvage pile elements and the outward nare ofthe pile adjacent the selvage extending laterally over the selvage cord.

6. A carpet strip having in the body portion thereof Wefts, binderwarps, stuer warps and pile elements, and having a selvage portioncomprising a selvage cord, stuffer warps, a row of selvage pile elementsand without binder warps, the selvage cord being snugly adjacent theroots of the selvage pile elements and the outward nare of the pileadjacent the selvage extending laterally over the selvage cord.

7. The method-of weaving a carpet strip which comprises forming the bodyportion thereof with wets, binder` warps, stuier warps and pileelements, and forming a selvage portion with wefts, a selvage cord,binder warps and a row of selvage pile elements and without certain ofthe type of warp present in the body of the carpet, and drawing theselvage cord snugly against the roots of the selvage pile elementswhereby the outward iiare of the pile adjacent the selvages extendslaterally over the selvage cord.
